COMBINED CAN OPENER AND SEALING DEVICE Filed Nov. 16, 1928 INV ZQR 4/ATTORNEY Patented Apr. 21, 1931 PATENT OFF-ICE HUGH T. HUGHES, O1CLEVELAND, OHIO COMBINED CAN QPENER AND SEALING- DEVICE I Applicationfiled November 16, 1828. Serial No. 819,898.

The objects of the invention are to provide an improvement in canopening devices by means of which a simple device attachable to any can,can be used to provide a ouring opening in the cover of the can ands1mu1- taneously therewith will provide an opening for the admission ofair in the cover, thus permitting the liquid therein to flow freely fromthe pouring opening; also the means employed for piercing the can aresubsequently employed to seal the opening they produce, and thus topreserve the contents of the can from fermentation.

The device is particularly applicable for domestic use when applied tocans containing evaporated milk, or syrup or other liquid foods, but canbe applied to any can containing liquids that are hermetically sealedand from which it is desired to exclude the air when only a part of thecontents has been' used.

The invention is illustrated in the accompanying drawings, hereinaftermore fully described, and particularly pointed out in the claims.

In the accompanying drawings; Fig. 1 is a planof a simple form of thedevice; Fig. 2 is a vertical section thereof; Fi 3 is a front elevationof the same; Fig. 4 1s a plan of an adjustable form of the device; Fig.5 is a vertical section thereof; Fig. 6 is a front elevation thereof,and Fig. 7 isa planpf a simple form of adjustable device. F1 8 shows amodified form of spring there or; Fig. 9 shows an ornamental holder fortable use; Fi 10 shows one manner of use of an attac ing clamp, Figs.11, 12 and 13' show pivoted levers and circumferential clamps. In theseviews A is the top of the can; B is a plate having downwardly turnededges C that are forced over the edges of the can to hold the plate inplace thereon; D is a metal bar or lever resiliently mounted upon" theplate B in such a manner that it can be tilted 4 vertically thereon, andis provided with spaced piercing points or projections E and Frespectively, which pass through openings G and H in the plate B andrest upon the cover of the can until the bar D is struck from above bythe hand or by a hammer or any convenient tool, when the points willpierce the cover at G and H.

When the bar is lifted the opening G can be employed for pouring, andair will be admitted through the opening H, and when released the barwill fall, and the points will reenter the openings they have reviouslymade, and will hermetically seal t cm, since they will fit the openingsclosely.

The bar is raised by pressing upon its outer end at I and may beresiliently connected with the plate by means of a spring J integralwith the plate, or may be plvoted upon the plate or attaching clamp andpressed upon by the spring K as shown in Figs. 8, 9, 11 and 12.

The pressure of the spring will retain the points pressed into theopenings so that air cannot enter the can.

In this manner the contents can be preseried from fermentation until ithas all been use In Figs. 4, 5, and 6 the modification of a longitudinaladjustment for the plate is shown to ada t it to several sizes of cansand the plate is ormed in two portions B, B, one portion sliding in idesB2 in the other portions, and provide with lateral lugs B3 that preventthe arts from separating.

The plate B is branched in front at B4 to provide a s ace between thearms for pouring so that the 'quid will not come in contact with theplate.

In Fig. 7 the plate is provided with a number of spring arms B5 whichare resilient enough to permit the plate to be attached to cans ofseveral sizes.

In Fig. 9 an ornamental holder M takes the place of the plate B, and ahandle N is attached thereto. In Fi s. 10, 11 and 12 a horizontal andcircum erential attaching clamp O is shown.

The device is simple, efiicient and of sli ht initial cost and fills amuch needed want or a can opening tool that will hermetically seal thecan after it has been opened.

In Fig. 12 the attaching-clamp is looped at I and the lever D isfpivoted in the loo Other modifications o the device may made within thescope of the claims.

Having described the invention what I claim-as new and desire to secureby Letters Patent is,

1. In a can puncturing and sealing device, a clampin support attachableto said can transverse y thereof and a bar or lever resiliently mountedto tilt vertically therein, said bar being provided with spaced verticalpointed projections in line therewith adapted to be forced through thecover of said can, when pressure is applied to said tilting bar aportion of said transverse support bein separated therefrom to form aspring, sai bar being mounted on said spring.

2. In a can puncturing and sealing device, a clamping support attachabletransversely to the cover of the can, and a bar resiliently mounted totilt vertically thereon, said bar being provided with spaced pointedprojections adapted to be forced through the cover of said can, whenpressure is applied to said tilting bar, and plate being made in twoportions adjustably connected together.

In testimony whereof I aflix my signature.

HUGH T. HUGHES.
